Controll Brightness of Video

Controll Brightness of Video

1. Point processing

• The operation sets the coordination pixel value of the output video from the translated coordination pixel value of the input video.

• The pixel value of result video should be in specific range(ex- gray scale).

2. What is controll brightness?

• The operation makes video more light or dark.

3. Addition computation to controll brightness of video

cv2.add(src1,src2, dst=None, mask=None, dtype=None) -> dst

• src1 : (input) first video or scala.
• src2 : (input) second video or scala.
• dst : (output) the result video of addition computaion.
• mask : Mask Video
• dtype : The type of output video ex) cv2.CV_8U etc *** Note
  • The scalar is tuple that is composed of one real value or four real vale.
